FRANK BEEMER,; OF PHILADELPHIA, PENNSYLVANIA AN'IVIFRICTION WHEEL Application filed June 25,

The principal object of the present invention is to provide antifriction wheels in which the clearance is fixed at the factory and can not be interfered with, in which the parts 5 are so permanently connected together that they can not be disassembled, interfered with or put out of adjustment after leaving the factory, and in which there is provided excellent lubrication and which are strong and adapted for heavy duty or service.

To these and other ends hereinafter set forth the invention may be said to comprise an antifriction wheelincluding an axle, a hub element of which the parts are nested, an annular groove and a confronting beveled flange providing a conical surface and arranged between the hub parts, roller elements interposed between'the hub and axle, and'a washer permanently mounted in said groove. and overlapping said flange.

The invention also comprises the improve-- ments to be presently described and finally claimed.

In the following description reference will be made to the accompanying drawing formin part hereof and in which i ig. 1 is a central sectional view of a wheel,

whic happens to be an overhead trolley wheel, embodying features ofthe invention and showing the dis ed washer ready f deformation and flattening.

Fig. 2 is a similar view showing the parts in assembled relation.

Fig.3 is an end view to right in Fig. 2. I

gig. 4 is a front view' of the dished washer, an

Fig. is a transverse sectional view of the same.

In the drawing 1 is the axle and it is tubular to provide an open ended lubricant receptacle 2 and a passage 3for the intro duction of lubricant. The axle is also pro videdwith a race 4 for the rolling elements 5'shown as balls. The hub element consists of two parts in nested relation. The outer looking from left part 6 is of'cup shape and the inner part 7 is of ring shape. Between the outer and innerrparts 6 and 7 there is an annular groove 8 and a confronting flange 9, and as shown part 7 there is a felt dust durable.

1927. Serial No. 201,408.

the, portion of the rin parts 7 adjacent to the flange 9 is bevele providing a conical face at 10. Between a shoulder 11 on the axle element 1 anda shoulder 12 on the ring guard 13. According to my invention when the described parts have been partly assembled as indicated in Fig. 1, the dished washer 14 is arranged as shown with its inner rim on the beveled or conical surface 10 and with its outer rim opposite the annular groove 8 and in abutment with the flange 9. Then, by the application of pressure in any suitable way the washer 14 is deformed and flattened so as to occupy the position shown in Fig. 2, in which it serves to lock permanently the two parts of the hub element together in such a way that they can not be again separated without cutting some of the parts, for example the washer 14:. The operation described is a simple one and easily performed and ithas the advantage that whatever-clearances may have been established are maintained and can not be interfered with. Moreover the wheel as a whole is strong and Good lubrication is provided from the open end of the described receptacle 2 by way of the clearance 15 provided between the axle and hub.

As. the dished Washer 14 is pressed over 89 the conical surface it is not only flattened but also expanded so that it is permanently mounted insthe groove 8, and overlying the face of the flange, permanently secures the two parts of the hub to other and also per manently secures the hu in position on the axle through the balls 5 ,andtheir races of which one is formed on the axle and of which the other is formed in part on each of the parts of the hub.

It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details of construction and arrangement and in matters of mere form without departing fromthe spirit of the invention which is not limited to such matters or otherwise than the prior art and the appended claim may-require.

I claim: An antifriction wheel structure mcluding p g a tubular axle element having a lubricant inlet and chamber and provided externally with a ball groove and with a shoulder, a hub element consisting of an outer portion having a half ball groove and an annular groove and of a ring shaped inner portion having a flange and a conical portion and a shoulder,

the hub and axle e1ement,bal1s in said races, and a washer expanded and permanently seated in said annular groove and engaging said flange. FRANK BEEMER.
